This happened to me today on a major highway. The Ford garage told me it is a transmission problem. Check transmission problem solutions here in this blog. Solenoids, etc. It means your transmission is slipping, that happens in a lot of Mercury mystiques. not all true there is a throttle position sensor or T.P.S. on your throttlebody try that its way cheaper than transmission

Rpm stands for revolutions per minute. This is talking about the revolutions the crankshaft goes per minute. The faster you go to more revoultions that are accomplished. Therefore the faster you go, the rpm goes up. And as you slow down it goes down.

What is the RPM needed to downshift a dump-truck?

It is not so much the proper RPM but the difference in RPM between gears. If you up shift at 1800 and going in next gear you are at 1200, then you have a 600 RPM split between gears. So downshifting you would be around 1200 and would while floating gears or double clutching bring the RPM's up to 1800-1900. Many trucks have RPM range stckers on the visors my old Mack was 1050-1750, that's a 700 RPM range, I would down shift when I hit 1050-1150, at 1150 I would have to bring the RPM's up to about 1850 to get it to go into gear.
